In a statement, Beyoncé’s company, Parkwood Entertainment, and Goldenvoice, the promoter behind the festival, confirmed that Beyoncé has pulled out of the event, over two weekends in April, “following the advice of her doctors to keep a less rigorous schedule in the coming months,” the statement said, according to The Associated Press.

“However,” the statement continued, “Goldenvoice and Parkwood are pleased to confirm that she will be a headliner at the 2018 festival. Thank you for your understanding.”

Beyoncé’s booking, announced in early January, was a major coup for Coachella, representing the first time that the 18-year-old festival had booked a major pop act — with a full choreographed show expected — for its main stage. (It was also one of the very few times that the festival had selected a woman as a headlining act.)

But her involvement was thrown into question when Beyoncé announced three weeks ago, via an Instagram post staged like a Renaissance painting, that she was expecting, a move that apparently caught the festival organizers by surprise.

The festival, scheduled for the weekends of April 14-16 and 21-23, in Indio, Calif., will feature Radiohead and Kendrick Lamar as its other headliners. Goldenvoice has not announced whether it will have a replacement for Beyoncé, and representatives of the company did not immediately respond to a request for comment on Thursday.
